Kim Kardashian and Kanye West’s surrogate is pregnant with their third child.

According to US Magazine, the 36-year old reality star and husband, Kanye, 40, began looking for a surrogate, and their surrogate, a San Diego mom in her late 20s, referred by an agency is three months along, which means they’ll likely welcome baby No. 3 in January 2018.

The surrogate has reportedly been a surrogate before, even appearing in a promotional video about the process with her own family.

The West’s who are parents to a daughter North, 4, and son Saint, 19 months, have agreed to pay $45,000 in 10 monthly installments of $4,500, according TMZ. In the case of multiples, Kardashian and West will fork over $5,000 per additional child. This is all in addition to the $68,850 deposit given to the agency.

Other stipulations in the contract include standard expectant-mother guidelines:

no drinking

no smoking

no drug use

no hot tubs or saunas

no raw fish

no handling cat litter.

Kim told talk show host Ellen DeGeneres in 2014, “I have so many siblings and I love it, they’re my best friends and I would love that for my kids.”

Kim had two pregnancies plagued by placenta accreta, a potentially life-threatening condition, which forced her and Kanye to consider alternative options, rather than enduring another high-risk pregnancy.
